Rat dental pulp stem cells: isolation and phenotypic characterization method aiming bone tissue bioengineering

ABSTRACT: Dental pulp stem cells (DPSC) have been showing a considerable potential for regenerative medicine. Pulps were collected from lower incisors (n=2) through direct access of the tooth pulp chamber. The isolated cells were cultured in alfa-MEM 10% FBS, in standard culture conditions. At the third passage, DPSC were characterized by flow cytometry (MHCI, CD54, CD73, CD90, CD45, CD11 and CD34); RT-PCR for Nanog gene; and their differentiation capacity in osteogenic, adipogenic and chondrogenic cell lines. Isolated cells exhibited adhesion capacity to plastic; fusiform morphology, and 80% ...
